BEER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 259,625, dated June 13,1882,

Application filed April 4, 1882, (No model.)

To all whom it may concern Be it known that I, LOUIS W INTERBAUER, acitizen of the United States, residing at New York, in the county andState of New York, have invented new and useful Improvements inApparatus for Supplying and Recovering Carbonic-Acid Gas, of which thefollowing is a specification.

The object of this invention is to produce an apparatus which shallanswer the dual purpose of supplying carbonic-acid gas to beerbarrels ontap and of recovering such gas when the beer has been drawn oft. It hasbeen common heretofore to supply carbonic-acid gas to beer-barrels,butno provision has been made for recovering such gas, it'being allowedto escape, and hence a loss or waste is incurred,

which is obviated by my invention.

This invention is illustrated by the accompanying drawings, in whichFigure l represents a front view, partly in section. Fig. 2 is across-section on the line 00 m, Fig. 1. Fig. 3 is a detail.

Similar letters indicate corresponding parts.

The letter A designates a reservoir or tank of ordinary form forcontaining the carbonicacid gas, and B a service-pipe emanating from thereservoir.

0 indicates a receiver embodying in its structure a suction-valve, D,and dischargevalve E, similar in construction and arrangement topump-valves; F, a return-pipe terminoting in the'suction-valve of thereceiver.

H denotes a two-way cock, having connected therewith both theservicepipe B and returnpipe F, such connection being made throughbranches B F, Fig. 2. In applying the apparatus to use this cook H isconnected to the barrel containing the beer-as, for example, by aflexible tube, I, and spigot J, Fig. 2and when the cock is turned to theposition shown in Fig. 2 the service-pipe B is opened and gas issupplied to the barrel from the reservoir A, while when the cock isturned to another position the return-pipe F is opened and the gas isconducted back from the barrel to the receiver G, into which it passesthrough the suction-valve D-namely, by displacing the valve, either pipebeing closed when the other is opened.

In practice the return-pipe F is opened when all the beer has been drawnfrom the barrel, and by its means I recover or obtain not only the gaswhich has been supplied to the barrel, but also that which has beengenerated by the beer, except that portion which has escaped with thebeer.

The gas passes from the receiver 0 into the reservoir A through thedischarge valve E, and in order to overcome or provide for an excess ofpressure in the reservoir I combine with the receiver a pumpingattachment operating to forcibly eject the gas. This attachmentconsists, in the example shown, ofa water-cock, K, which is connected tothe lower part of the receiver and through which water is admittedthereto under pressure at the proper time, so that as the water rises inthe receiver it compresses and displaces the gas. Another effect of thisattachment is that when the water is permitted to escape a partialvacuum is produced in the receiver, whereby the gas is drawn into itfrom the barrel. a desirable contrivance, because the required purposecan thereby be accomplished by simply connecting it with a water-supplyfaucet in a building; but a piston or other equivalent means also can beused, the receiver being in either case converted into a pump.

In the branch B of the service-pipe are arranged two valves, N O, (seeFig. 2,) both having a common chamber, P. The valve N is a check,serving to prevent the beer from rushing from the barrel through theservice-pipe B to the reservoir by effervescence, and such valve issupported by a spiral spring, 0', rest- The water-cook K is ing on thebottom of the chamber P. The valve O is a regulating device fordetermining the pressure of the gas supplied to the barrel, and it issupported by an elastic diaphragm, s, having combined therewith aspring, t, whereby the valve is held open against a fixed pressure ofthe gas, while when its pressure rises the valveis permitted to close,due to the action of the gas.

In the return-pipe F is arranged a suctionvalve, U, Fig. 1, and when thebarrel has been entirely emptied of the gas by the action of thereceiver pumping attachment this valve opens automatically and admitsair, thus preventing the oreation of a vacuum in the barrel. I arrangethe suction-valve U in a horizontal portion of the return-pipe and belowthe plane of its inner surface, so that the valve remains closed whilethe gas is being drawn from the barrel.

In the branch F of the return-pipe is arranged a stopcock, V, wherebythis pipe can be shut ofl' irrespective of the main or two-way cock.

If desired, the pipes B F may be connected with the spigot Jindependently of each other, in which case two cocks, B F, are used, oneto each pipe.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore described, of the gasreservoir, the service-pipe emanating from the reservoir, the receiverhaving a suction-valve and dischargevalve, the return-pipe terminatingin the sue tion-valve of the receiver, and the couplingpipe extendingfrom the discharge-valve of the receiver to the reservoir.

2. The combination, substantially as hereinhefore set forth, of thereceiver having a suction-valve and discharge-valve and the pumpingattachment of the receiver with the reservoir, the coupling-pipe, theservice-pipe, and the return-pipe.

3. The combination, substantially as hereinbefore described, of thereceiver having a suetion-valve, discharge-valve, and water-cock withthe reservoir, the coupling-pipe, and the return-pipe.

4. The combination, substantially as hereinbefore set forth, of theservice-pipe, the returnpipe, and the two-way cock having both pipesconnected thereto with the reservoir, the receiver having asuction-valve and dischargevalve, the coupling-pipe extending from thedischarge-valve of the receiver to the reservoir, the service pipeemanating from the reservoir, and the return-pipe terminating in thesuction-valve of the receiver.

5. The combination, substantially as hereinbefore set forth, of theservicepipe having arranged therein the cheek-valve N, the gaspressnreregulating valve 0, and the chamber common to both such valves with thereservoir and receiver.

6. The combination, substantially as hereinbefore set forth, of thereturn-pipe and the suction-valve arranged therein with the receiverhaving a suction-valve and discharge-valve, the return-pipe connected tothe suction-valve, and the pumping attachment of the receiver.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
